Momonoki Morax

Morax Momonoki is one of the prestigious professors at Barbirus Academy, a school in the demon world.

Though being a teacher around her students, Momonoki is shown to be somewhat shy as she shows to have feelings for Naberius Kalego, a fellow teacher. She absolutely adores Kalego's familiar form, and takes any chance she gets to gush over seeing it.
